The Pro-Graad 2-Piece Brake Hub Resurfacing Starter Kit is a solution for cleaning your vehicle’s hub and wheel mating surfaces. In the Box, you’ll find one 1/4" hex shank holder, and one 1-1/2” diameter cleaning disc. Note that the kit includes only ONE cleaning pad. Replacement Pads Number 1-1/2” Diameter 46150, 2” 46200. Compatibility is key with this kit, as it supports use with cordless and power drills. The hollow center design of the cleaning disc ensures it can slide safely over wheel studs without damaging the threads, preserving the integrity of your wheel studs during operation. For rust and corrosion removal, the cleaning disc effectively eliminates rust, corrosion, and debris without causing excessive material removal or gouging, ensuring that the wheel’s integrity is maintained. To achieve optimal performance, the tool should be operated at LOW SPEEDS below 10,000 RPM and in a FORWARD (clockwise) direction only. This kit is ideal for applications in automotive, SUVs, light trucks, utility trailers, UTVs, and ATVs, providing quick and effective cleaning of wheel-end mating surfaces, around wheel studs, and particularly for hub cleaning and resurfacing.
